De scrip tion
The output of the receiver is an analog,
low impedance, voltage source capable
of driving an amplifier or level translating
circuitry for use on various data formats
and data rates up to 35 MBaud.
The receiver is comprised of a high
speed, low noise, photodiode coupled to
a transimpedance amplifier which
produces an output voltage proportional
to the input light amplitude. This hybrid
approach solves many of the problems of
high speed data link designs by placing a
pre-amplifier close to the photodiode.
The level amplification produced by the
transimpedance amplifier makes the
output signal much less susceptible to
interference which is a problem often
found at high data rates and in high EMI
environments.
